<P>PROBLEM TO BE SOLVED: To provide a mobile radio terminal device capable of conducting a synchronism by a synchronizing signal corresponding to even two different synchronous techniques. <P>SOLUTION: In a transmitter, a transmission is conducted by using the synchronizing signal linking a plurality of blocks composed of mutually different synchronous-code series in the order replacing the blocks in a first half section and a second half section. In a receiver, synchronous detectors 232 and 233 corresponding to both systems of a replica base system corresponding to the synchronizing signal and a delay correlation base system respectively are fitted, and the replica base system selectively conducts a synchronous detection by the delay correlation base system. <P>COPYRIGHT: (C)2008,JPO&INPIT |
